    DETO LIGHTS?

    what rpm's are you lights coming on at

    #1 cyl.=
    #2 cyl.=
    #3 cyl.=

    Some people's lights are going to come on at diff. times because of all the diff. in mods we have.
    to fix the problem of detataion "when the lights come on" should we retard timing alittle or add fuel or add octane to our fuel?
    Mark?
    Nils?

    I'm only getting 7064 +/- a few so I'm not a good test yet. But the Deto lights flash occasionally while just holding it wide open, and it is totaly random. I haven't touched the RR map at this point

    the light flashing intermittently is no problem. its when they stay on for a second or two(or stays on ) you need to adjust. i would add fuel first and if the light doesn't settle down then take away timing. the pump gas maps were written for 94 octane and the race maps for 100 octane. if you are using 92 for the pump map you may want to take a degree or two off the whole map

    I know this is a dumb question, but when you all say "add fuel" are you saying go to a higher octane gas? (not add octane to 92 to get 94)
